The Hawaii Biological Survey, established by the Hawaii State Legislature in 1992 as a program of Bishop Museum, is an ongoing natural history inventory of the Hawaiian Archipelago. It was created to locate, identify, and eval - uate all native and nonnative species of flora and fauna within the state; and by State Law to maintain the reference collections of that flora and fauna for a wide range of uses. In coordination with related activities in other federal, state, and private agencies, the Hawaii Bio logical Sur vey gathers, analyzes, and disseminates biological information necessary for the wise stewardship of Hawai‘i’s biological resources. An intensive and coordinated effort has been made by the Hawaii Biological Survey to make our products, including many of the databases supporting the papers published here, available to the widest user-community possible through our web server. Products currently available include taxonomic authority files (species checklists for terrestrial arthropods, flowering plants, nonmarine snails, marine invertebrates, fossil taxa, and ver - tebrates), bibliographic databases (vascular plants, nonmarine snails, and insects), speci - men databases (fungi, fish, invertebrates, portions of the insect collection) and type spec - imens (entomology; botany—including algae and fungi; and vertebrates), collections data (lists of holdings for select groups of flies as well as Cicadellidae and Pentatomidae), detailed information and/or images on endangered, threatened, and extinct plants and ani - mals; as well as our staff publication lists. Additional reference databases include: the list of insect and spider collections of the world (based on Arnett, Samuelson & Nishida, 1993, Insect and spider collections of the world ) with links to institutional web almost 6,400 authors who have described flies.

In this paper, two new naturalized records, 14 new island records, two range extensions, and one notable rediscovery are report - ed. Additionally, seven taxa are reported as adventive and showing signs of naturalization. A total of 25 taxa in 16 plant families are discussed. One taxon is endemic, and another is pos - sibly indigenous; the remainder are introduced. Collections cited were made on the islands Moloka‘i, Maui, and Hawai‘i. Information regarding the formerly known distribution of flowering plants is based on the Manual of the Flowering Plants of Hawai‘i (Wagner et al . 1999) and information subsequently published in the Records of the Hawaii Biological Survey . Voucher specimens are deposited at the Bernice Pauahi Bishop Museum Herbarium Pacificum (BISH), Honolulu, with duplicates at the National Tropical Botanical Garden (PTBG), Lāwa‘i, kaua‘i. A few specimens may be at only one or more facilities; only in these cases will the herbarium acronym be cited. Amaranthaceae Gomphrena globosa L.

Thus the impact of management on two xerothermophilous terrestrial gastropod species, Zebrina detrita and Caucasotachea UNESCO Wienerwald vindobonensis, and on land snails in general, was evaluated in the vineyard area of northern Vienna. This area belongs to the buffer zone of UNESCO Wienerwald Biosphere Reserve in Austria. A total of 18 sites were investigated, including vineyard Biosphere Reserve embankments and dry meadows with different intensity levels of clearing and grub- bing in recent years. Occurrence of both target species and their ability to recolonize Mountain range newly created habitats were assessed. Snails are able to colonize new areas in direct vicinity of existing populations that are above detection level. Only annually repeated Alps clearing of meadows and embankments with originally strong shrub coverage result- ed in a visible effect.

    A Napaeopsis species (Gastropoda: Pulmonata: Enidae) from the Peloponnese, Greece E. Gitt enberger Gitt enberger, E. A Napaeopsis species (Gastropoda: Pulmonata: Enidae) from the Peloponnese, Greece. Zool. Med. Leiden 82 (27), 20.vi.2008: 271-273, fi gs 1-2.— ISSN 0024-0672. Edmund Gitt enberger, Nationaal Natuurhistorisch Museum Naturalis, P.O. Box 9517, 2300 RA Leiden, The Netherlands (gitt [email protected]). Key words: Gastropoda; Pulmonata; Enidae; Napaeopsis; new species; Greece. Three Napaeopsis species were known from Greece. A fourth one is described now as N. mennoi spec. nov. It is the fi rst record of the genus for the Peloponnese. Introduction Describing new species is facilitated considerably when there is a recent mono- graphic treatment of the genus to which they belong. Here I profi t from the revision of the Greek species of some genera of Enidae, including Napaeopsis Sturany & A.J. Wag- ner, 1914, by Bank & Menkhorst (1992). In that paper, aft er a general introduction, three species, one of which with two subspecies, are reported from Greece. During a fi eld trip with my friend and colleague Dr. Menno Schilthuizen in the northwestern part of the Peloponnese, shells of clearly a fourth Napaeopsis species were found. This constitutes the fi rst record of the genus for the Peloponnese, since according to Bank & Menkhorst (1992: 109), the nominal taxon described as Buliminus (Ena) cefalonicus var. conemenosi by Boett ger (1885: 121) from the northern part of the peninsula is not a Na- paeopsis. It belongs in the synonymy of Ena m. monticola (Roth, 1856). The new species is described below.

Rundell. Suggested Citation USFWS. 2020. Species Report for Eua zebrina. Version 1.1. May 2020 (Version 1.1). U.S. Fish and Wildlife Service, Pacific Islands Fish and Wildlife Office, Honolulu, HI. 33 pp. Primary Authors Version 1.1 of this document was prepared by Adam E. Vorsino, Fred Amidon and James Kwon of the Pacific Islands Fish and Wildlife Office, Honolulu, Hawaii. Preparation and review was conducted by Gregory Koob, Megan Laut, and Stephen E. Miller of the Pacific Islands Fish and Wildlife Office. ii Executive Summary This Species Report summarizes the status of Eua zebrina, a tropical tree snail in the family Partulidae, based on the most recent information. For E. zebrina, this is information from Cowie and Cook, 1999. To assess the viability of E. zebrina, we used three conservation biology principles: resiliency, redundancy, and representation, or the “3Rs”. The viability of E. zebrina is evaluated with reference to the resiliency of its populations, its redundant occurrence across its native range, and its representation in its known habitat types. Eua zebrina is known only from the islands of Tutuila and Ofu in American Samoa. Many of the 120+ partulid species are restricted to single islands or isolated groups of islands. The Samoan partulid tree snails in the genera Eua and Samoana are representative of this endemism and isolation. Historically, Eua zebrina was abundant on the island of Tutuila, and later reduced to its current rare level by the introduction of non-native snail predators.

ZooKeys 614: 27–49. doi: 10.3897/zookeys.614.8807 Abstract We describe a new stylommatophoran land snail of the family Partulidae from Palau. The new species has a combination of morphological and ecological characters that do not allow its placement in any existing partulid genus, so we describe a new genus for it. The new genus is characterized by a large (18–23 mm) obese-pupoid shell; smooth protoconch; teleoconch with weak and inconsistent, progressively stronger, striae; last half of body whorl not extending beyond the penultimate whorl; widely expanded and reflexed peristome; relatively long penis, with longitudinal pilasters that fuse apically into a fleshy ridge that divides the main chamber from a small apical chamber; and vas deferens entering and penial-retractor muscle at- taching at the apex of the penis.

The sites were chosen according to their proximity of factories and other potential sources of pollution. Totally 8463 individuals were collected and 14 species identified (12 species of snails and 2 species of slugs) belonging to six families: Milacidae, Helicidae, Subulinidae, Cochlicellidae, Enidae and Hygromiidae. Among the species identified 4 are constant: Helix aspersa (Müller, 1774), Otala lactea (Müller, 1774), Trochoidea elegans (Gmelin, 1791), Rumina decollate (Linnaeus, 1758), 3 are accessory: Helix aperta (Born, 1778), Helicella virgata (Da Costa, 1780) and Theba pisana (Müller, 1774), and 7 are accidental: Cepaea vendobonensis (Ferussac, 1821), Zebrina detrita (Müller, 1774), Dupotetia A zonata (Pallary, 1926), Cochlicella barbara (Linnaeus, 1758), Milax gagates (Draparnaud, 1801), Milax nigricans (Phillipi, 1836), Cepaea nemoralis (Linnaeus, 1758). The specific richness of the gastropod species was found to vary between sites and by season. General seasonal peak was recorded during Spring and Winter while the lowest abundance observed during Summer. Helix aspersa is the most abundant species in all prospected sites and will be used as a bioindicator of soil pollution.

In this study, four new Napaeus species from the Canary Islands are described. Shell drawings of the 56 known Napaeus species were obtained from shell photographs for comparison. Differences between some genital system character-states of the species described here and those of the original subgenera descriptions are evident. Consequently, in the absence of phylo- genetic analyses, the new species are not assigned to the Napaeus subgenera. In addition, the possible relationships among Macaronesian enids are preliminarily evaluated. Within the Macaronesian region, enids are exclusively present in the Canaries and the Azores. The absence of enids from Madeira, combined with the differences in genital anatomy between the Canarian and Azorean enids and the relatively large distance between these archipelagos, may indicate different immigration pathways (Africa/Europe, respectively) and possibly different phylogenetic origins for the Canarian and Azorean enid populations.

Few studies on the subject are done in south Bulgaria between 2000 and 2013: by WELTER-SCHULTES (2000, 2001), • Locality №1 - Upper Thracian Lowland, HAUSDORF (2003), NEKOLA et al. (2013), 100-150 m a.s.l., grasslands near an GIOKAS et al. (2014). Currently, there are no agricultural area at the village of studies concerning the shell size of Zebrina Podslon, 36 shells; detrita Müller, 1774 and its variations at • Locality №2 - Upper Thracian Lowland, different habitats and altitudes but many 100-150 m a.s.l., grasslands near an forms and subspecies were described agricultural area at the east part of Stara (WELTER-SCHULTES, 2012).

C. barbara was found for the first time in south-eastern of Anatolia in April 2019 in the campus area of the Dicle University in Diyarbakır, Turkey. C. barbara is admitted as a harmful organism and classified as an agricultural pest in most of the countries. Species in this genus have been intercepted in postal packages, soil, and cargo as well as can be easily transported with plants, building materials, household goods, etc. Above all, it is an intermediate host of nematode and fluke parasites of livestock. Knowing the distribution of this species will not only contribute to the registration of a new species in the list of gastropods of the region but also facilitate the control of the species across Turkey. Keywords: Cochlicella barbara, Intermediate host, Pest snail, Diyarbakır Introduction (Larbaa and Soltani, 2013).
